Hello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it. The grass is very thin and I was told that is because oak trees turn the soil acidic. I had lime put down last year but the grass still looks the same.ello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it.

When planting acid-loving plants, mix sphagnum peat moss with soil at a 50/50 ratio in the planting hole and apply a 2-inch layer over the soil surface. The peat helps to lower the soil's pH, allowing the plants to absorb nutrients such as iron.
